My invention relates to musical instruments, and has among its objects and advantages the provision of an improved saxophone unit.

An object of my invention is to provide novel means for grouping a plurality of saxophones in such manner as to facilitate playing thereof by one player. The Saxophones are grouped on a suitable support with two saxophones arranged for finger manipulation of the keys thereof, with the other saxophone provided with novel foot operated means for key manipulation.

In the embodiment selected to illustrate my invention, Figure 1 illustrates three saxophones H), i2 and Is as being grouped for playing by one player. The saxophones are mounted on a standard l6 attached to a base 18 through the medium of a flange 20 secured to the base by screws 22. Flange 20 includes a socket 24 into which the lower end of the standard I6 is pressed to be supported in an upright position. Standard l6 may comprise tubular material for the sake of lightness and suitably ornamented.

In Figures 1, 10, l1 and 12 1 illustrate the 5 manner in which the saxophones are connected with the standard. To the upper end of the standard I6 I secure a bar 26 intermediate its ends. Bar 26 is arranged at right angles to the standard 15 and carries arms 28, 30 and 32 to 10 which the saxophones l0, l2 and l4,respectively, are connected to be supported in such manner as to bring their mouthpieces 34 into simultaneous playing relation. Arms 28, 30 and 32 are identical in construction and operation so that the 15 description of one will apply to all. Figure 12 illustrates the arm 30 which arm is slotted at 36 for the reception of a screw 38 threaded into the bar 267 A washer 40 is positioned between the head 42 of the screw 38 and the arm 30. Thus 20 the arm 30 may be shifted longitudinally or rotated about the axis of the screw 38 to secure precise alignment of the arm. Tightening of the screw 38 firmly secures the arm 30 in the desired position.

To the wall 44 of the saxophone I2 I secure two spaced cars 46 which are bored at 48 for the reception of the vertical stem 50 of the horizontal rod 52 provided with a ball 54. Ball 54 is located inside the socket section 56 at one end of the 30 arm 30 and within the socket section 58 in the nature of a cap having flanges 6D cooperating with flanges 62 on the socket section 56 for consummating a clamped connection with the ball 54. Flanges 60 and 62 are provided with aligned openings for the reception of bolts 64 through the medium of which the socket sections 56 and 58 are brought into pressure relation with the ball 54. Both of the ears 46 may be provided with set screws 66' to secure the stem 50 against relative rotary movement as well as to secure the saxophone associated with that stem in different positions of adjustment vertically. It will thus be seen that the saxophone l2 may be adjusted through rotation of the ball 54 in the associated socket and that the saxophone may be adjusted about the stem as an axis, in addition to being adjustable vertically of the stem. Thus I provide means for securing precise positioning of the saxophone. Arms 30 may be shifted to various 50 angular relations to secure proper spacing between the saxophones Ill, l2 and I4.

Saxophone I2 is equipped for foot operation, While saxophone I0 is provided with means to facilitate manipulation of keys by the righthand 56 which are manipulated by the left hand in standard equipment. No changes are made in the saxophone I4. With respect to saxophone I0, high D, Eb and high F keys indicated at 58, I and I2, respectively, in Figure 3 are provided with actuating means adapted for manipulation by the right hand. To the D key button 74 I connect an arm I6 which extends about the instrument sufficiently far to bring the key within reach of the right hand. Eb button I8 is provided with arms 80 and 82, with the arm 82 arranged for right hand manipulation. An arm 84 is connected with the bar 86 manipulated through the medium of the high F button 88. Arm I6 extends over the bar 86, while arms 89 and 82 extend over the button 14 and the bar 86, respectively. Arm 84 extends underneath the bar 90 to which the button 78 is connected.

When a high F tone is played, all three keys 68, I0 and I2 must be open. Normally these keys remain closed. Opening of the three keys may be accomplished with the use of but one finger by pressing on the button 88. Such pressure on the button 08 moves the arm 84 upwardly for lifting the key 7!] simultaneously with elevation of the key F. As key I0 is elevated, the arm 80 exerts pressure on the button I4 for simultaneously opening the key 68. When a high Eb tone is played, both keys 68 and I0 must be opened. Exerting pressure on the finger 82 will open the key I0 and simultaneously open key 68 because of the arm 86 which presses down on the button '54. Arms I6 and 82 are spaced from the bar 85 sufiiciently far to be in the clear of the bar in all positions of the keys 68 and 70 when manipulated through the medium of the arm 82. It will thus be seen that keys 68, I0 and I2 may be manipulated by the right hand, rather than by the left as is conventional practice in standard Saxophones.

In standard Saxophones, the player can go no lower than the tone G through the use of one hand. In order to secure tones below G with one hand only, I add an arm 92 to the Gt button 94 and an arm 90 to the Ct" button 98. An arm IE0 is attached to the B button I02. The lower F and E keys are indicated at I04 and I06, respectively. Keys F and E are located far down on the instrument. Arms 92, 96 and I00 are arranged within playing range of the buttons I6, 82 and 88. C-i' button 98 is connected with a rotary shaft I08 for operating the Cit key (not shown). I utilize shaft I08 for operating the low F key I04. Key I04 is connected with a rotary shaft H0 and is conventionally depressed through the medium of the button II2. To the shaft II 0 I connect an arm I I4 which lies underneath an arm IE6 connected with the shaft I08, so that pressure on the arm 96 will move the arm IIG downwardly on the arm II 4 for closing the key I04. Thus the key I04, which is located at a considerable distance down the instrument, may be manipulated through the arm 96 by the little finger of the right hand arranged within playing range of the buttons 76, 82, 88 and the arm 92. Low E key I06 is connected with a rotary shaft IIS and is ordinarily manipulated through the medium of the button I20. To the shaft H0 I connect an arm I22 which lies underneath an arm I24 connected with the rotary shaft I26 operatively connected with the button I02. Thus the key I06 may be closed by exerting pressure on the arm I00.

To the conventional shaft I28, which operates the high E key I39, I connect a button I32 which renders the key operable from a position high up the instrument. As a rule, this key is operated with the second hand located near the bottom of the instrument. Button I32 renders the key accessible to the right hand.

Referring to Figure 5, saxophone I2 is provided with two parallel channel-like supports I34 and I36 spaced longitudinally of the saxophone. These supports are made secure to posts I38 welded or otherwise secured to the saxophone at their inner ends and connected with the supports at their outer ends through the medium of screws I40. Support I34 is associated with the A, B and G keys I42, I44 and I46, respectively. Ordinarily, these keys are normally open in conventional saxophones. In the instant case I arrange the keys so as to be normally closed to facilitate foot manipulation.

Figure 6 illustrates the B key I44 in its normal position for closing the tone opening I48. The key may be pivoted about its conventional axis I50. I provide a spring I52 which is cooperable on the arm I554 secured to the instrument and a projection I56 secured to the arm I58 for urging the key to a closed position. Key B as well as keys A and G are conventional in construction with the exception of reversing the spring tension so as to hold these keys normally closed. In the keys A, B and G I connect arms I60, I62 and I 64, respectively. Figure 6 illustrates the arm I62 as being attached to its associated key I44 through the medium of screws I66. All the arms I60, I62 and I64 are identical in construction and operation so that the description of one will apply to all.

In Figure 6, the arm I62 is notched at connection with the looped end i2 2 passing around a grooved wheel I14 rotatably mounted on a shaft H6 in the nature of a screw connected with the channel-like support I34. Arm I62 is of such length as to bring the pull line I12 into right angular relation with the axis of the grooved wheel I14. Thus a pull on the downwardly extending run I18 of the line I72 will pivot the key I44 to an open position.

Arm I 60 associated with the A key is connected with a pull line I80 passing over the grooved wheel I 82 in the same manner as the pull line I12. Thus a pull on the downwardly extending run I84 of the pull line I80 will open the A key. Arm I64 is connected with a pull line I86 passing over a grooved wheel I 88. A pull on the downwardly extending run I90 of the line I86 will open the valve I46. Keys A, B and G must be closed when the G tone or lower tones are played. The reversed spring action elTective on these keys holds the keys closed, which keys are opened through manipulation of foot operated pedals connected with their respective pull lines.

Support I66 is associated with D, E and F keys I92, I94 and I96, respectively. Figure 7 illustrates the F key I96 as being provided with an arm I08 secured thereto by screws 200. Key I96 is changed from its conventional construction only in the provision of the arm I98, which arm is notched at 202 for connection with the loop 204 on one end of a pull line 206 which passes over a grooved wheel 208 rotatably related to the support I 36 in the same manner as the wheel Il4 of Figure 6. Pull line 206 includes a downwardly extending run 2I0 in the manner of the lines I12, I80 and I86. Key I96 is normally open and is closed by exerting a pull on the run 2I0. Key I94 is provided with an arm 2I2 connected with a pull line 2I4 passing over a grooved wheel I68 for H0 of a, pull line 2I6 rotatably related to the support I36. Line 2I4 includes a downwardly extending run 2I8. Similarly, key I92 is provided with an arm 220 connected with a pull line 222 passing over a grooved wheel 224 carried by the support I36. Line 222 includes a downwardly extending run 226. Thus the keys I92, I94 and I96 may be closed by exerting a pull on their respective lines.

To the lower end of the support I36 I secure a plate 228 provided with eyelets 230 through which all the pull lines extend. Thus the plate 228 holds the lines in grouped relation and permits the lines to be pulled to an angle to the vertical beneath the plate, as indicated at 232' so as to permit the lines to be passed through eyelets in a plate 236 anchored to the base I8 considerably to one side of the grouped saxophones supported by the base. Figure 5 illustrates each line as being provided with a swivel 238 interposed in its respective line and having a threaded slack take-up 240 to permit accurate adjustment of the lines. Each swivel 238 includes a hook 242 for detachable connection with the loop 244 in one section of the divided line.

Figure 8 illustrates the arrangement of the pedals which connect with the pull lines for operating keys of the saxophone I2. Line I12 connected with the key I44 passes through an eyelet 246 in the plate 236 and is connected at 248 with an arm 250 arranged at right angles to a bar 252 pivctally journaled in bearings 254 mounted underneath the base I8. Base I8 is flanged at 256 and provided with short pads 258 so as to afford space for the rod 252 and other mechanism mounted underneath the base. Rod 252 includes a short arm 260 to which a link 262 is pivotally connected as well as with a pedal 264 pivotally connected at one end to the base I8, as at 266. An opening 268 in the base provides accommodation for the link 262. A tension spring 210 has one end connected with a screw 212' in a collar 214 secured to the rod 252 by the screw. The other end of the spring is anchored to a lug 216 fixed to the bottom face of the base I8 for exerting a rotary pull on the rod 252 for urging the arm 250 in the direction of the base I8. Thus a downward thrust on the pedal 264 will exert a pull on the line I12 for opening the key I44.

Pull line I80 associated with the key I42 passes through an eyelet 218 in. the plate 236 and is connected at 280 with an arm 282 formed at one end of a rod 284 rotatably journaled in bearings 286. Rod 284 includes an arm 288 pivotally connected with a link 290 extending through an opening 294 in the base I8 for connection with the pedal 296 which is pivotally connected with the base in the same manner as pedal 264. A tension spring 298 is connected with ascrew 300 carried by a collar 302 fixed to the rod 284 by the screw. The opposite end of the spring is hooked into a lug 304 attached to the base I8 for rotating the rod 284 to move the arm 282 in the direction of the base I8. Thus downward pressure on the pedal 296 will move the arm 282 for exerting a pull on the line I80 for opening the valve I42. Line I86 passes through an eyelet 305 in the plate 236 and is connected at 306 with an arm 308 carried by a rod 3I0 rotatably journaled in bearings 3I2. An arm 3I4 is formed at one end of the rod 3I0 and is pivotally connected with a link 3I6 extending through an opening 3I6 in the base I8 for connection with the pedal 320. One end of a tension spring 322 is connected with a. set screw 324 in a collar 326 fixed to the rod 3I0 by the set screw. The opposite end of the spring 322 is connected with a lug 323 attached to the base I8. Spring 322 exerts a rotary pull on the rod 3I0 for urging the arm. 308 in the direction of the base I8. Arm 308 is bent to extend underneath the arm 250, as at 330, while the arm 282 is bent to extend over the arm 308, as at 332.

With the keys I42, I44 and I46 closed, the tone produced is G. To produce the tone A, the key I46 alone is opened through pressure on the pedal 320. To play the tone B, both keys I42 and I46 are opened. This may be accomplished by pressing the pedal 296 alone, since the arm 282 will press down on the arm 308 so that both keys will be opened. To play the tone C, the keys I44 and I46 are opened, with the key I42 remaining closed. This is accomplished by pressing down on the pedal 264 alone. Movement of the arm 250 will exert pressure on the arm. 308 for opening the valve I46 also, with the valve I42 remaining closed. To make the tone Cit, all three keys I42,

M4 and I46 must be opened. This is accomplished by pressing down on the pedal 246 with the toe and down on the pedal 264 with the heel of that foot. Both arms. 250 and 282 extend underneath the arm 308 so that the latter will be pressed down simultaneously with the other two keys.

Arms 266, 268 and 3M may be provided with stops 334 for engaging the bottom face of the base I8 to accurately position the associated line pulling arms. The stops may comprise screws having threaded relation with their respective arms. It is advisable to provide each screw with padding for engagement with the base I8 to dampen the sound.

Pull line 222 associated with the key I92 passes through the eyelet 336 in the plate 236 and is connected at 338 with an arm 340 connected at right angles with a rod 342 rotatably journaled in bearings 344. Rod 342 includes an arm 346 pivotally connected with a link 348 extending through an opening 350 in the base I8 for connection with the pedal 352. One end of a. tension spring 354 is connected with a set screw 356 carried by a collar 358 secured to the rod 342 by the set screw. The other end of the spring 354 is connected with a lug 366 attached to the base I8 for rotating the rod 342 to move the arm 346 in the direction of the base. Thus the key I92 may be closed by exerting a pull on the line 222 through the medium of the pedal 352.

The line 2I4 connected with the key E94 passes through the eyelet 362 in the plate 236 and is connected at 364 with an arm 366 carried by a rod 368 rotatably journaled in bearings 310 attached to the base I8. Rod 368 is provided with an arm 312 pivotally connected with a link 314 extending through an opening 316 in the base I8 for connection with the pedal 318. Arm 312 is urged in the direction of the base I8 through the medium of a tension spring 380 having one end connected with the set screw 382 carried by the collar 384 secured to the rod 363 by the set screw. A lug 386 is attached to the base I8 and is connected with the other end of the spring 380 for holding the latter under tension so that the spring tension will urge the arm 312' in the direction of the base I8.

The pull line 206 associated with the key I96 passes through the eyelet 388 in the plate 236 and is connected at 390 with an arm 392 attached to the rod 394 rotatably journaled in bearings 396 attached to the base I8. I pivotally connect the arm 398 with the link 400 similarly connected with the pedal 402. Arm 398 is urged in the direction of the base I8 through the medium of a tension spring 404 connected with the set screw 408 carried by the collar 488 made secure to the rod 394 by the set screw. Spring 484 is hooked into a lug 4I8 attached to the base I8.

Normally open keys must be closed securely to avoid a leak. Too much closing pressure will cut the pad covering. In connection with the foot operation of the normally open keys I92, I 94 and I96, the arms 340, 366 and 392 comprise fiat spring material. When the pedals associated with these spring arms are pressed, the arms pivot far enough to assure effective closing of the associated keys, but the tension of the spring arms is such as to permit the arms to yield at the moment that the keys have been closed sufiiciently secure. Thus the tension of the spring arms is such as to relieve the key or pad covering from damage incident to excessive closing pressure. Pull lines 206, 2I4 and 222 require no slack in the open positions of the associated keys.

The arms 346, 312 and 398 are provided with stops 4I2 corresponding to the stops 334. These stops are adjusted so as to stop the upward movement of the associated arms immediately before their respective keys are completely open. Thus the spring tension of the conventional springs associated with the keys holds the lines sufficiently taut.

In connection with normally closed keys, it is essential that the pull lines be so adjusted with the keys at rest as not to restrain the keys from complete closing. The keys must be securely closed so as to prevent leaks. It is, therefore, essential that the associated pull lines must embody a. certain degree of slack, but the slack must be limited so as to prevent the lines from jumping their associated grooved wheels.

With reference to the keys I42, I44 and I46, Figure 13 illustrates a slack take-up which may be provided for each of the arms 248, 282 and 388. Pull lines I12, I38 and I86 may be utilized without slack take-up means but operation under such conditions requires considerable adjustment. Figure 13 illustrates the manner in which arm 258, as an example, may be provided with a weak, fiat spring M4 for taking up slack in the line I12. One end of the spring 4I4 is fixedly connected at MS with the arm 258, and the arm is bored at M8 for loosely receiving the line. The end of the line is provided with a ball 428 which lies underneath the flat spring 4I4 and is fixedly connected with the line. The spring is bored for the reception of the line. Figure 13 illustrates the arm 258 in its normal position at which time the key I44 is closed. Spring 4I4 bears against the ball 420 for placing the line I12 under the necessary tension. When the pedal 264 associated with the line I12 is pressed down, resistance ofifered by the key I44 will flex the spring 4I4 against the arm 250 after which the arm pressure exerts a pull on the line I12 for opening the key. In the normal position of Figure 13, spring 4I4 exerts suihcient pressure on the line I12 to effectively hold the key I44 in closed position, but the pressure is slight so as not to open the key.

Figure 5 illustrates an arm 422 as being connected with the shaft 424 which operates the G4: key 426. To the outer end of the arm 422 I connect a pull line 428 which is passed over one of the usual key guard bars 430 and extended downwardly for passage through the eyelet 432 in the plate 236. Pull line 428 is connected at 434 with an arm 436 carried by a rod 438 rotatably journaled in bearings 440. Rod 438 includes an arm 442 pivotally connected with a link 444 extending through an opening 446 in the base I8 for pivotal connection with the pedal 448. Thus the normally closed G# key 426 may be opened by exerting a pull on the line 428 through pressing down on the pedal 448.

I connect a tension spring 450 with a lug 452 attached to the base I8 and with a set screw 454 carried by a collar 456 attached to the rod 438 by the set screw. Spring 458 urges the arm 442 in the direction of the base I8, and the arm is provided with a stop 458 corresponding to the stops 334.

In Figure 14, I illustrate the button 468 which is utilized for finger manipulation of the octave key (not shown) associated with the saxophone I2. Button 468 is connected with the shaft 462 in the usual manner. To the saxophone I2 I connect a bracket 464 (see Fig. 14) which carries a grooved wheel 466. To the button 468 I connect a pull line 468 which passes over the grooved wheel 466 and downwardly through an eyelet 469 attached to the support I34, then through a perforation in the plate 228 and through the eyelet 418 in the flange 28 and a similar opening in the base I8 for connection at 412 with an arm 414 of a rod 416 rotatably journaled in bearings 418. Rod 416 is provided with an arm 480 which is pivotally connected with a link 482 extending through the opening 484 in the base I8 for connection with the pedal 486.

I connect one end of a tension spring 488 with a lug 498 attached to the base I8, and the other end of the spring is connected with a set screw 492 carried by a collar 494 secured to the rod 416 by the set screw. Spring 488 moves the arm 414 in the direction of the base, and this arm may be provided with a stop 486 corresponding to the stops 334.

It will be noted that the tension spring associated with each of the rods 252, 284, 3I8, 342, 388, 394, 438 and 416 is connected with its respective rod adjacent one of the supporting bearings for that rod. The tension spring operates to eliminate rattling between its respective rod and the associated bearing in addition to placing the rod under rotary tension. Each of these ing to prevent rattling of the rod in the event of a loose fit.

Figure 9 illustrates a tension spring 498 as having one end connected with the set screw 500 in the collar 502 secured to the rod by the set screw. The opposite end of the spring is hooked over a pin 504 fixed to the base I8. In connection with the rod 284, a tension spring 586 is connected with the rod in the same manner as the spring 498 and is hooked over the pin 504. A tension spring 588 is connected with the rod 3I0 in the same manner as the spring 498 and is hooked over the pin 584. Rod 342 is provided with a tension spring 5I0 connected with the rod in the same manner as the spring 498 and is hooked over a pin 5I2 anchored to the base I8. A spring SM is hooked over a pin 5I6 anchored to the base I8 and connected with the shaft 368 in the same manner as the spring 498. Rod 394 is connected with a spring 5I8 in the same manner as the spring 498 and is hooked over a pin 528 anchored to the base I8. Spring 522 is hooked over a pin 524 anchored to the base I8 and connected with the rod 438 in the same manner as the spring 498. Similarly, rod 416 is connected with a spring 526 hooked over a pin 528 and connected with the rod in the same manner as the spring 498.
